The Dartmouth Ice Core Lab has state-of-the-art ice core processing, sampling, and analysis capabilities including a Kovacs Mark III drill with sidewinder system, freezer facilities for core and sample storage, an ice core melting system with discrete sampling (see our publication describing this system here), ion chromatography for major ion analysis, and a Picarro L2130-i laser water isotope (δ18O and δD ratios) analyzer. We also have the capability to analyze ice samples for trace metal concentration through collaborations with the Dartmouth Trace Element Analysis Laboratory directed by Brian Jackson, and to analyze rare and complex elements including Platinum Group Elements (Pt, Os, Ir) using the Thermal Ionization Mass Spectrometry Laboratory directed by Mukul Sharma.

ice core collection

Collecting an ice core in the Dry Valleys of Antarctica using a PICO hand auger. The ice core lab has access to a Kovacs Mark III hand auger (similar to the PICO pictured above) recently purchased by Prof. Hawley.

ice core on melter

An ice core slab melting into the custom-made ice core melt head, which collects pristine meltwater from the center of the ice core for chemical analyses.
ice core melter system

The ice core meltwater is pumped from the melt head to be collected in pre-cleaned bottles by three fraction collectors under HEPA clean benches.
